CAN-FUSING MACHINE.

SPECIFICATION forming part of Letters Patent No. 773,800, dated November1, 1904.

Application filed October 17, 1902.

To all whom it may concern:

Be it known that I, AUeUsTUs Lorz, a citi-. zen of the United States,residing in the city and county of San Francisco, State of California,have invented certain new and useful Improvements in Can-FusingMachines; and I do hereby declare the following to be a full, clear, andexact description of the same.

The present invention is designed to fuse the ends or heads ontocan-bodies, said bodies being delivered to the fusing-machine with theends applied thereto and a thin strip or ribbon of solder secured to theend portions of the can-body, the invention consisting in soconstructing the can runway and propelling means for the cans as toprovide for the escape of a head freed from the traveling cans, therebypreventing a clogging of the cans, which results by a freed head lodgingwithin and blocking the runway, and in so arranging the propelling meansas to relieve the cans of the weight thereof, whereby injury or damageto the cans as propelled through the machine is provided against,thereby reducing the output of leaky or defective cans.

The usual means for propelling the cans through an end-soldering machineconsists of an endless-chain conveyer which bears upon the upper surfaceof the cans and by reason of its weight holds the cans onto thecan-guideway and forces the cans to rotate thereon, the cans being heldbetween the chain conveyer and the guideway. The objection to thismanner of conveying the cans through the soldering mechanism is that theweight of the conveyer mashes a number of the cans which it propelsthrough the soldering mechanism, thereby causing the discharge of anumber of defective and leaky cans. The present invention is designed toovercome this defect incident to end-soldering machines. It consists ofan endless conveyer provided with a series of independent seats for thecans, within which seats the cans rotate freely as carried through thecan-guideway, the rotation of the cans being due to their weight solelybearing upon the guideway while being acted upon by the propellingstrain of the conveyer. Instead of the action of heating means whichmelts a ribbon of solder previously applied to the cans, so that thesame may flow into the end joint of the rotating cans to solder the endsthereto.

To comprehend the invention, reference should behad to the accompanyingsheet of drawings, Wherein Figure 1 is a plan view of the machine. Fig.2 is a side view thereof. Fig. 3 is an end view of the fuser viewed fromthe discharge end thereof. Fig. 4 is a detail view of a sec tion of thecan-conveyer. Fig. 5 is a side view in elevation of the device disclosedby Fig. I of the drawings, and Fig. 6 is a perspective view of the'canwith the ends applied thereto and the ribbons of solder in positionto befused into the end joints of the can.

In carrying out the invention the can-bodies A are first run through asuitable machine (not shown) that applies a band or ribbon a of solderto the surface thereofa slight distance from the end of the can-bodyequal to the depth of the flange a of the can heads or ends A, whichheads or ends are then applied to the open ends of the can-body. Whenthus soldered and headed or ended, the cans are ready to be subjected tothe action of the fusing-machine in order that the ribbon to of soldermay be melted and run into the joint of the can ends or heads.

The fusing-machine comprises a suitable frame 1, supported by standardsor legs 2. To brackets 3 I, projecting from each end of the frame, thebearings 5 6 are secured, within which work the cross-shafts 7 8. Thebearing-5 for shaft 7 is adjustably secured to bracket 3 by means ofset-screw 9, so that longitudinal adjustment may be given thereto. Tothe shaft 7 is attached a sprocket-gear 9 and to shaft 8 a similar gear10. Over these gears work the endless-chain conveyer 11, the tension ofwhich is regulated by means of the adjustable bearing 5. The endlessconveyer works within the frame 1, being driven from drive-shaft 12 bymeans of pinion 13, secured
